Speed of Sound in Air:
The speed of sound in air is given as 333 m/s.
Fundamental Frequency of an Open Pipe:
The fundamental frequency of an open pipe is given as 333 Hz.
Calculation of Pipe Length for 2nd Overtone:
To find the length of the pipe required to produce the 2nd overtone, we need to understand the concept of harmonics in pipes.
- Harmonics in Pipes:
When a pipe is open at both ends, it can produce harmonics or overtones. The fundamental frequency is the first harmonic, the first overtone is the second harmonic, the second overtone is the third harmonic, and so on.
- Relationship between Frequency and Length:
The fundamental frequency of an open pipe is determined by its length. The formula for the fundamental frequency of an open pipe is given as:
f1 = v / (2L)
where f1 is the fundamental frequency, v is the speed of sound, and L is the length of the pipe.
- Calculating the 2nd Overtone:
The 2nd overtone is the third harmonic, so its frequency can be calculated as:
f3 = 3 * f1
Substituting the given values, we have:
f3 = 3 * 333 Hz = 999 Hz
- Finding the Length of the Pipe:
Now, we can rearrange the formula for the fundamental frequency to find the length of the pipe required for the 2nd overtone:
L = v / (2 * f3)
Substituting the given values, we have:
L = 333 m/s / (2 * 999 Hz) = 333 m/s / 1998 s^-1 = 0.1665 m = 0.17 m (rounded to two decimal places)
Therefore, the length of the pipe required to produce the 2nd overtone is approximately 0.17 meters or 17 cm.
However, the given answer is 0.5 m, which does not match the calculated value. It is possible that there was an error in the answer provided.
